Since its founding in 2015, 1X has been at the forefront of developing advanced humanoid robots designed for household use. Our mission is to create an abundant supply of labor via safe, intelligent humanoids.

We strive for excellence in all we do, solving some of the hardest problems in robotics with the world’s most talented individuals. Every part of our robots is designed and produced in-house—from motor coils to AI—reflecting our vertically integrated approach. At 1X, you’ll own real projects, be recognized for your achievements, and rewarded based on merit.

We believe the best work is done when collaborating and therefore require in-person presence in our office locations.

We are looking for a supplier development engineer to help shape our supply chain to deliver world-class robotics at scale. Ensure precision components for complex systems like 50+ DoF biped humanoids meet the highest standards. In time, your work will help bring safe, intelligent humanoids into homes around the world.

Responsibilities:

• Partner with engineering and sourcing teams to select suppliers based on capabilities in motor and magnetic component manufacturing
• Evaluate suppliers’ motor winding, rotor/stator assembly, and magnet bonding processes
• Ensure consistency in torque-speed characteristics, thermal performance, and EMI compliance
• Support rotor balancing, bearing preload setups, and encoder integration
• Lead the supplier industrialization process from design through production ramp-up
• Support suppliers with tooling, equipment, and process qualifications
• Assess supplier readiness for vehicle builds and manage production risk
• Drive the APQP process and support PPAP through the start of production
• Train suppliers on 1X’s quality systems and review part quality documentation
• Lead root cause and corrective action efforts for supplier quality issues
• Monitor and report supplier quality metrics to ensure ongoing improvement
• Apply lean and quality tools to drive continuous improvement across the supply base
• Travel up to 40%, domestically and internationally, sometimes on short notice

Must-Haves:

• Bachelor’s degree in Mechanical, Industrial, or a related engineering field
• 6+ years of experience in quality, supplier quality, or manufacturing—ideally in automotive, aerospace, or medical devices
• Hands-on experience launching new products and improving quality systems
• Skilled in problem-solving methods like Six Sigma, 8D, and root cause analysis
• Proficiency with quality tools such as FMEAs, control plans, SPC, MSA, and capability studies
• Understanding of manufacturing processes related to electronics, batteries, and precision sensors
• Strong experience with supplier audits, APQP, PPAP, and production ramp-ups
• Ability to read engineering drawings and use GD&T; knowledge of ISO 9000 and IATF 16949 quality systems

Nice-to-Haves:

• Certifications like CQE, Six Sigma Green Belt, or Quality Auditor
• Experience with tooling and fixture validation
• Proficiency in Microsoft Office; Google Workspace experience

Compensation

At 1X your work and results will be rewarded with a total rewards package consisting of a base salary, stock options and benefits. Base salary range is $110,000 to $180,000. Your actual salary will be based on your knowledge, skills and experience.
